I cut This way, That way, Upside down and Sideways. I thought I had it all down but nothing was making sense. I truly made an impressive pile of kindling.
Then, I thought I had it. I tried to assemble and discovered another error in my logic.
Here is a sample:
That’s not bad for practice but I soon discovered the error of my ways.
The angle where the two boards are joined was cut at 13.28 degrees or my absolute best estimate. My machines are just not that precise. Why 13.28? It’s 58.28 degrees minus 45 degrees. 58.28 degrees was specified in a question I asked about a month ago. So far, I don’t see anything wrong with that angle.
Here’s another shot of that end.
I also double mitered the end pieces. 36 for the pentagon angle and 13.28 for the inside angle. As it turns out, you only want the 36 degrees there. When you try to put the pieces together, the second miter cut messes up the angle. Here’s a shot of 3 sides of the pentagon.
If you will notice, the angle is not quite right. Sides 5 and 6 won’t fit.
I know what to do tomorrow. There won’t be a bunch of experimental cutting. If I’m lucky, I’ll be able to connect 5 pentagons. I’d be a lot less dry about this If I had anything to show for my efforts. At least I have a little knowledge. Wish me luck.
-- Thanks for all the lessons!
